I am looking to compare ballistics for a .300 Win and didnt find anything in other threads about this, forgive me I am sure its somewhere.
Anyhow looking at the listed BC for the Sierra 180 and 190 HPBT Match King I noticed that one tends to improve with velocity and one gets worse and I wondered why this is?
I want to know how to select the most Accurate BC but EXBAL wont allow me to pick 180 HPBT at the velocity that I want (2950-3000) I need this number to be exact as it is the foundation of everything.
How do I get an accurate BC? and should I be using the G5 function for this bullet?
